The investigation into whether University of Michigan football star Taylor Lewan was involved in a Dec. 1 assault on South University Avenue in Ann Arbor is now in the hands of prosecutors.

Ann Arbor police Detective Lt. Robert Pfannes said Thursday afternoon police have finished their investigation and turned it over to the Washtenaw County Prosecutor’s Office. Prosecutors will determine whether charges will be filed against Lewan or anyone else.

Police said Lewan was in the area of an assault reported at 12:30 a.m. Dec. 1 in the 1200 block of South University Avenue. The incident took place after Ohio State University defeated Michigan at Michigan Stadium and the incident involved Ohio State fans.

Two Buckeye fans reported being assaulted on the block that night. On Dec. 24, police confirmed Lewan’s role in the incident was being investigated.

A police statement read Lewan was one of several subjects in the area of the incident. No one was arrested at the time and the investigation didn’t wrap up until Thursday, Pfannes said.

Lewan has repeatedly denied any involvement in the incident. At the National Football League Combine last month, Lewan said he was trying to break up an altercation between other people.

“I wasn’t in any fight of any kind,” Lewan said in a press conference. “I was actually breaking something up and some guy said that I slugged him. But that’s not who I am off the field, that’s not the kind of person I am. I might seem that way because of the way I play football, but that’s not who I am as a person.”

Lewan, who was a senior during the 2013 season, was a two-time All American at Michigan and is projected to go early in the first round of May’s draft. He’s considered one of the top three offensive tackles in the draft.
